The head shape of an old duck is a common K-line shape. K-line pattern refers to a common K-line pattern, which is formed after the dealer pulls up the position and sees that the retail investors have not left the market, so that the stock price breaks through the 5-day line and the 10 line and shakes out short-term chips. It looks like a duck. It is a classic form formed by a series of trading behaviors such as opening positions, washing dishes and pulling up. Without breaking through the support level, the shape of the old duck head oscillated out chips, gained support on the 20th and 30th lines, contracted at the end of the adjustment, then slowly rose, attracted attention below the high point, and then came out from the flat mouth to form the old duck head, and the dealer immediately made a second wave of quotes. The shape of the old duck head is actually the process of the main force forcibly collecting chips. Duck neck (opening a position to attract chips) and duck head (washing dishes) shrink files, forming sesame seeds, and the stock price slowly picks up (attracting chips).

1. The stock price of an old duck head must run above the lifeline. In the process of stock price adjustment, it cannot fall below the support of the 60-day line. When making the "head", we should pay attention to the shock behavior of the main force and grasp the selling points (such as the dead fork of the 5-day line and the dead fork of the 10 line and macd). When making a duck's mouth, that is, the emergence of "sesame seeds", we must grasp the buying points at this time (the golden fork on the 5th and 10 line, the golden fork signal of MACD). In the process of operating the duck head, we must grasp the band operation. The duck's head must be heavy, and the volume of the duck's mouth must be shrinking, which means that the probability of the stock price rising later is huge!

2. The drawing method of K-line chart in stock market and futures market includes four data: opening price, highest price, lowest price and closing price. All K-lines are centered around these four data, reflecting the general situation and price information. If you put the daily K-line chart on a piece of paper, you can get the daily K-line chart, and you can also draw the weekly K-line chart and the monthly K-line chart. First, we find the highest price and the lowest price of the day or a certain period of time, and connect them vertically into a straight line; Then find out the opening price and closing price of the day or a certain period of time and connect the two prices into a long and narrow rectangular column. If the closing price of the day or a certain period of time is higher than the opening price (that is, lower prices and higher prices), we will indicate it in red or leave a blank on the column, which is called "positive line". If the closing price of the day or a certain period of time is lower than the opening price (that is, high opening and low going), we will use green to indicate it, or paint the column black, and this column is the "negative line".
